NCT ID NCT07672119
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at heart-related side effects in older men with advanced prostate cancer treated with enzalutamide or darolutamide. Researchers will analyze existing health records from 3,000 men aged 55 and older to compare rates of heart attacks, strokes, and heart-related deaths. No new treatments or visits are involved—just a review of past data to guide safer treatment choices.
